Se si tratta di un file ASCII utilizzare il seguente codice:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://news.google.com/news?hl=en&topic=t&output=rss');
$fp = fopen('rss.xml', 'w');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_exec ($ch);
curl_close ($ch);
fclose($fp);

Se invece si tratta di un file binario utilizzare quest’altro codice

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/serverfile.zip');
$fp = fopen('file.zip', 'wb');
curl_setopt($ch, CURLOPT_FILE, $fp);
curl_exec ($ch);
curl_close ($ch);
fclose($fp);

$number = 15;
printf("Decimal: %d", $number);	//Decimal: 15
printf("Binary: %b", $number);	//Binary: 1111
printf("Double: %f", $number);	//Double: 15.000000
printf("Octal: %o", $number);	//Octal: 17
printf("String: %s", $number);	//String: 15
printf("Hex (lower): %x", $number);	//Hex (lower): f
printf("Hex (upper): %X", $number);	//Hex (upper): F

$main_img = "Porsche_911_996_Carrera_4S.jpg"; //immagine principale
$watermark_img = "watermark.gif"; //use GIF or PNG, JPEG has no tranparency support
$padding = 3; //distance to border in pixels for watermark image
$opacity = 100; //image opacity for transparent watermark

$watermark = imagecreatefromgif($watermark_img); //create watermark
$image = imagecreatefromjpeg($main_img); //create main graphic

if(!$image || !$watermark)
	die("Error: main image or watermark could not be loaded!");

$watermark_size = getimagesize($watermark_img);
$watermark_width = $watermark_size[0];
$watermark_height = $watermark_size[1];  

$image_size = getimagesize($main_img);
$dest_x = $image_size[0] - $watermark_width - $padding;
$dest_y = $image_size[1] - $watermark_height - $padding;

//copy watermark on main image
imagecopymerge($image, $watermark, $dest_x, $dest_y, 0, 0, $watermark_width, $watermark_height, $opacity);

//print image to screen
header("content-type: image/jpeg");
imagejpeg($image);
imagedestroy($image);
imagedestroy($watermark);
